AUTOMATIC MEASURING DEVICE FOR LIQUIDS. Q

$PECIFICATION forming part of Letters Patent No. 316,910, dated April 28, 1885.

Application filed October 20, 1884.

To all whom, it may concern.-

Be it known that I, JEAN PRAX, of the city of Montreal, in the district of Montreal and Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in Automatic Measuring Devices for Liquids and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to that class of liquidmeasuring devices in which smaller vessels adapted to contain specified quantities are connected to a larger vessel or tank, so that the contents of the latter will be automatically fed into the measuring-vessel, out of which the liquid is drawn.

The object of my invention is to provide a simple and inexpensive self-measuring apparatus which will entirely avoid waste, and of such construction that the measuring attachments will be contained within the main tank, and thus obviate all danger of the same being damaged or put out of order.

For full comprehension of myimprovements, reference must be had to the accompanying drawings, forming part of this specification, in which letters of reference similar to those hereinafter used indicate like parts.

Figure 1 is a vertical section of a measuringtank illustrating myinvention; Fig. 2, a crosssection of same on line a: 51 Fig. 1; Fig.3, an enlarged sectional view of faucet and its con nections, and Fig. 4. an enlarged sectional detail showing air-tube and cap covering the same.

A represents the main tank or reservoir, of any suitable size, construction, and material, and having by preference a funnelshaped cover, B, made in one with or separate from the tank, placed far enough below the rim 0 to avoid splashing out of the liquid while it is being poured therein. The mouth of the funnel is provided with suitable stopper, D.

His the measuring vessel or chamber adapted to contain a specified quantity of the liquid, this measuring vessel or chamber being situated near the bottom of the tank A, close to its walls, and connected with a sleeve or tube, a, which projects through the tank-wall, its outer end being provided with afiange, 19. To

this flange p is bolted, as at g, a ring, f, which encircles a faucet, I, in such manner that the latter may turn therein while being held properly in place. This faucet I is made of asuitable handle, a, and a tapering spigot, b,which latter fits into the sleeve n and is adapted to be revolved therein. In this spigot are formed two openings, (1 and e, that marked (1 being situated near the inner end of an open-ended vertical tube, K, arranged within the tank A and connected to the sleeve n, while the opening 6 is situated near the outerv end of the spigot, being placed at right angles to d and arranged so as to be turned opposite an outletpipe, L, which also connects with the tube at at its under side.

The measuringwheel H is usually inclined toward the faucet I, as shown, for convenience in emptying and to admit the necessary air. I connect to the vessel H, near its upper corner, an air-tube, J, which extends upward inside the tank A and through the cover B, its outlet being preferably constructed as shown Viz., with an enlarged mouth, F, having one or more perforations, j, through its sides, and with a rotary cap, 2', fitting over said mouth and provided with perforations m corresponding to j. The space occupied by this capped outlet may be partitioned off from the funnelshaped cover B, as shown.

If desired, a double bottom may be made for the tank, the inner one being placed level with the open end of the tube K, which will project through I it. Furthermore, two or more measuring-vessels of different capacities may be arranged in connection with the one tank,

as will be readily understood.

The operation of my invention is as follows: The spigot being in the position shown in Fig. 3viz., with the opening d opposite the lower end of the tube K, and the liquid in the tank A covering the latter-the measuring-vessel H and spigot b will be full, the capacity of both being considered as making up the specific quantity. The capo will then be turned so as to bring the openings m and j opposite to each other and admit air to the tube J. By giving the handle a a quarter-turn the inlet at at will be closed and the opening 6 brought opposite to the outlet-pipe L, through which the measured contents will flow. A quarter-turn of the spigot in the reverse direction will re store the parts to their first position, and the measure H will again be filled, the air-outlet then being closed.

I am aware that a tank containing a measure and having a faucet, and also a pipe connecting the interior of the tank with the faucet, are not broadly new.

What I claim is as follows:

1. The combination, in a measuring-vessel, of a tank, A, a measure, H, inclosed within the same, a tube, a, extending from the measure through the side of the tank, a hollow plug, a, within such tube, a stand-pipe, K, between the measure and the wall of the tank J. PRAX.
